Overview
The LTC2171IUKG-12 is a 4-channel, simultaneous sampling 12-bit analog-to-digital converter (ADC) designed by Analog Devices Inc. This component is optimized for digitizing high frequency, wide dynamic range signals, making it ideal for demanding communications applications. It features exceptional AC performance, including a 71dB signal-to-noise ratio (SNR) and a 90dB spurious free dynamic range (SFDR). The ultralow jitter of 0.15ps RMS enables excellent noise performance, particularly in undersampling IF frequencies.
